gases from the engine in a lateral direction below the level of the aeroplane deck more especially when the latter is to be used to receive or launch an aeroplane. Preferably 10 the ship is provided with telescopic or like,

disappearing funnels which, when extended, enable the smoke or exhaust gasestobe discharged in the usual manner. Y

The lateral discharge shafts may be formed as branches from the above chimneys or funnels which are preferably provided with or incorporated in some known form of spark catcher and in a convenient arrangement an operative connection is provided between the lateral branches and the collapsible funnels which ensures these branches being automatically opened when the funnels arelowered and vice versa. v

The disappearing funnels are in some cases furnished with small openings to allow sufficient smoke or exhaust gases to escape in an upward direction through the aeroplane landing deck so as to indicate the direction of the wind. 7

Two constructions according to this invention are diagrammatically illustrated by way of example in the accompanying drawings, in whic 7 Figure 1 is a side elevation of the ship provided with an aeroplane deck,

Figure 2 is a cross-section on the line-1 1 of Figure 1 on an enlarged scale, and Figures3 and '4 show in vertical section and plan respectivel on an enlarged scale a special form of co apsible funneL- The ship diagrammatically illustrated is provided with an aeroplane landing and launching deck 1 and is fitted with four Diesel engines 2, the exhaust gases of which escape vertical exhaust pipes 4. The exhaust pipes are provided with end pieces or funnels 5 branches 6 through which the smoke or ex:

' These funnels are preferably 'mountedin spark arresters new which they arelowered and with which the lateral branches connect.

" In the particular construction illustrated in Figures 3'and 4, the funnels are furnished with radial openings for the outlet'of the smoke or exhaust gases which for the main part thus leave therfunnelsin a lateraldirection, but in addition the upper ends of the funnels are furnished with flat plates 10' adapted when lowered to lie flush with the level of; the aeroplane deck and provided with" relatively small perforations so that even when the funnels are loweredsome smoke still escapes upwards and indicates to the pilot of'any aeroplane wishing to land on deck the exact direction of the wind.
